Abstract
The utility model discloses a compressor fixing device for air conditioning passenger cars. The compressor fixing device for the air conditioning passenger cars comprises a variable-speed device, a compressor assembly, a generator assembly and a rotating support shaft, wherein the variable-speed device, the compressor assembly and the generator assembly are fixed at the upper part of an upper baseplate; the rotating support shaft is fixed at the upper part of a lower baseplate; the upper baseplate is in flexible connection with the lower baseplate through a flexible shock-absorbing cushion; the cross section of an outer ring of the flexible shock-absorbing cushion is square; the outer ring of the flexible shock-absorbing cushion is fixed to the lower part of the upper baseplate through a fixing clip; the rotating support shaft penetrates an inner ring of the flexible shock-absorbing cushion and is fixed to a support plate of the lower baseplate; and the two ends of the rotating support shaft are fixed through bolts respectively. When the compressor works, more than 90 percent of vibration generated during the working of the compressor is absorbed by the flexible shock-absorbing cushion; and when a belt of the variable-speed device is tensioned, the belt can be automatically tensioned by an engine through rubber between the inner ring and the outer ring of the flexible shock-absorbing cushion, and the recoil force generated by the engine can be effectively buffered.
Description
Technical field
The utility model relates to a kind of air conditioned passenger car compressor fixing, is meant a kind of air conditioned passenger car compressor fixing on the vehicle compressor driving system especially.
Background technology
Consult Fig. 1, at present, the air-conditioning of China's air conditioned passenger car overwhelming majority is not merely vertical unit, and the air-conditioning compressor unit is fixed on driving engine one side, is driven by automotive engine drive wheel 11.Because the turn up of automotive engine less than the desired speed of air-conditioning compressor 13, needs between to increase a transmission system 12; When the generating capacity steam supply car of the entrained electrical generator of automobile itself and air-conditioning use simultaneously in addition, need to increase an electrical generator 14, drive electrical generator 14 by compressor 13.Transmission system 12, compressor assembly 13, alternator assembly 14 are fixed on the top base plate 16 of same support, and are arranged in parallel in storehouse behind the driving engine; The rotation pivot shaft 17 that is fixed on lower raft 18 tops was gone here and there the resilient cushion member 19 that is fixed on top base plate 16 belows and is formed and be rigidly connected; Be compensation driving engine the moving of resilient mounting on resilient cushion member 19, fixedly the compressor fixing of transmission system 12 must rotate with the mobile of driving engine, and the compression spring 151 on the compressor fixing just plays this effect.
Existing compressor fixing has following deficiency:
1. compressor, compressor bracket, chassis are that rigid construction connects, and it is uncomfortable that the vibrations that produce during compressor operating can cause part to take the passenger.
2. the vibrations of compressor can cause air-conditioning self parts to damage easily, particularly compressor clutch bearing and the flexible pipe that is connected compressor.
3. transmission system, compressor, electrical generator, tensioner spring assembly are to be arranged in parallel in storehouse behind the driving engine, cause the support left and right directions can be very long, and under the effect of tensioner spring, bracket assembly will have a certain amount of distortion.
Summary of the invention
The purpose of the utility model is to provide a kind of air conditioned passenger car compressor fixing that absorbs the vibrations of compressor generation and cushion the recoil of engine producing.
For solving the problems of the technologies described above, the solution of the utility model is:
A kind of air conditioned passenger car compressor fixing; Comprise the transmission system, compressor assembly, the alternator assembly that are fixed on base plate top, top; Be fixed on the rotation pivot shaft on lower raft top; This top base plate is connected through flexible cushion blocking is soft with lower raft, and the outer ring cross-sectional plane of this flexibility cushion blocking is square; The outer ring of said flexible cushion blocking is fixed on the bottom of top base plate through clips, and the inner ring that said rotation pivot shaft string is crossed flexible cushion blocking is fixed in the stay bearing plate of lower raft, and these rotation pivot shaft two ends are respectively by bolt.
Said rotation pivot shaft is threaded with the inner ring of flexible cushion blocking.
Said flexible cushion blocking is made up of rubber.
After adopting such scheme, the utility model produces following good effect to the air conditioned passenger car compressor bracket:
1. owing to be soft the connection between top base plate and the swivel bearing axle, improved the working condition of compressor greatly, to compressor clutch, compressor shaft gland, the corrugated hose of connection compressor has played good protection, has prolonged its tenure of use.
2. the whole compressor support is able to because having lacked the tensioner spring device simplify; And the flexible cushion blocking that increases has the automatic tension function under locking state, can control belt to move reposefully, does not beat; The control belt is non-slip, thereby improves the transmission efficiency of belt widely; Prolong the service life of belt simultaneously.Flexible cushion blocking is non-maintaining, so just can reduce the maintenance cost of compressor bracket.
3. the vibrations that produced when having solved the air conditioned passenger car compressor operation can obviously improve the comfort level of taking the passenger to passenger's influence (reducing vibration more than 70 percent than original rigidly connected support).

The specific embodiment
In order further to explain the technical scheme of the utility model, come the utility model is carried out detailed explaination through specific embodiment below.
Consult accompanying drawing 1, Fig. 2, accompanying drawing 3, the transmission of air conditioned passenger car compressor is adorned 2 and is comprised, is fixed on transmission system 22, compressor assembly 23, the alternator assembly 24 on top base plate 26 tops; Be fixed on the rotation pivot shaft 27 on lower bottom 28 tops, top base plate 26 and lower raft 28 are through flexible 29 soft connections of cushion blocking, and outer ring 41 cross-sectional planes of flexible cushion blocking 29 are square; Because outer ring 41 is square; Increase the area of contact of flexible cushion blocking 29 and lower raft 28, be difficult for making 26 upsets of top base plate, under the situation that has reduced tensioner spring assembly 15; Play the effect that prevents 26 rotations of top base plate, saved material and can reach same effect.
The outer ring 41 of flexible cushion blocking 29 is fixed on the bottom of top base plate 26 through clips 310; The top of top base plate 26 is transmission system 22, compressor assembly 23, alternator assembly 24 fixedly; And be arranged in parallel in storehouse behind the driving engine; Rotation pivot shaft 27 was gone here and there the inner ring 42 of flexible cushion blocking 29 and was fixed in the stay bearing plate 311 of lower raft 28, will rotate pivot shaft 27 with two bolts and fixedly make it can not the front and back play.
Be connected through the soft of flexible cushion blocking 29 between the top base plate 26 of fixing compressor and the lower raft 28, the vibrations that when compressor operating, produce all will be absorbed by flexible cushion blocking 29 more than 90 percent; Driving engine 21 with regard to ability automatic tension belt, also can cushion the recoil that driving engine 21 produces through the rubber between flexible cushion blocking 29 Internal and external cycles (can be other flexible material) effectively behind the belt tension of transmission system 22.
The natural frequency of flexible cushion blocking is 2.2Hz, and damping rate is 0.2-0.3.
The embodiment that the above is merely the utility model is not to this case design-calculated restriction, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
